Getting the ingredients right for this salad is simple but essential. Each element plays a unique role in balancing taste, texture, and color—from the earthy roasted veggies to the zesty, herby dressing that ties everything together beautifully.

Cauliflower florets (about 6 cups): The star vegetable, offering a delicate, nutty bite when roasted to perfection.
Baby potatoes (1.5 lbs, quartered): Creamy and tender, they add a hearty, comforting texture without needing peeling.
Extra-virgin olive oil (3 Tbsp.): Essential for roasting, it helps develop that irresistible golden crust and deep flavor.
Kosher salt (3/4 tsp. for roasting + 1/4 tsp. in dressing): Enhances the natural flavors, ensuring every bite is perfectly seasoned.
Ground coriander (3/4 tsp.): Adds a subtle, citrusy warmth to the roasted veggies.
Ground cumin (1/2 tsp.): Brings an earthy complexity that complements the cauliflower beautifully.
Cracked black pepper (1/2 tsp. for roasting + 1/4 tsp. in dressing): Offers just the right peppery kick for balance.
Arugula (2 handfuls): Adds a peppery, fresh crunch that lifts the dish and contrasts with the warm roasted vegetables.
Tahini (3 Tbsp., well-stirred): Creamy and nutty, this sesame paste forms the base of the dressing, bringing richness and depth.
Fresh lemon juice (2 Tbsp.): Brightens the dressing with lively acidity that keeps the salad fresh.
Fresh tarragon (1 Tbsp., finely chopped): The herbaceous, slightly sweet flavor of tarragon makes this dressing truly special and memorable.
Minced garlic (1 tsp.): Adds savory punch and warmth to the dressing.
Granulated sugar (1/2 tsp.): Balances out the acidity and rounds out the flavor of the dressing.
Water (2 Tbsp.): Used to thin the dressing just enough for easy tossing without losing creaminess.

The bowl rests on a white marbled surface, with two yellow lemon wedges placed beside it at the bottom left and a fresh green leaf at the bottom right. In the top right corner, part of a wooden bowl holding a lemon half is visible. A few small purple and green basil leaves are scattered near the upper left edge of the bowl.

Step 1: Roast the Vegetables

Preheat your oven to 425ºF, and get ready for that heavenly aroma of roasted veggies! Spread the cauliflower florets and quartered baby potatoes on a large rimmed baking sheet. If your pan feels crowded, don’t hesitate to use two baking sheets—crowding prevents proper roasting. Drizzle everything with extra-virgin olive oil, then sprinkle kosher salt, ground coriander, ground cumin, and cracked black pepper evenly over the vegetables. Toss well to ensure every floret and potato piece is coated in that magical spice blend. Roast for 30 to 40 minutes, giving everything a good toss halfway through so they roast evenly. You want the potatoes tender and the cauliflower lightly charred, developing those irresistible caramelized edges.

Step 2: Prepare the Tarragon-Tahini Dressing

While the veggies are roasting, whip up the dressing that takes this salad to the next level. In a small bowl, combine the well-stirred tahini, fresh lemon juice, finely chopped tarragon, minced garlic, granulated sugar, salt, and pepper. Whisk everything together until it’s smooth and creamy. Then stir in 2 tablespoons of water to thin the dressing slightly, making it perfect for coating all the roasted goodness without being too heavy. The fresh tarragon really shines here, infusing the tahini with an irresistible herbal brightness.

Step 3: Assemble the Salad

Once your vegetables have roasted to perfection, transfer them to a large serving platter. Spoon half of the tarragon tahini dressing over the warm veggies and toss gently to combine, letting that luscious sauce soak into every bite. Add the peppery arugula last, tossing once more just enough to incorporate without wilting it. Finish by drizzling the remaining dressing over the top and a final crack of black pepper. Serve immediately to enjoy the satisfying contrasts of warm roasted veggies and fresh greens with the creamy dressing tying it all together.

How to Serve Roasted Cauliflower and Potato Salad with Tarragon Tahini Recipe

Garnishes

For a beautiful presentation and added texture, consider sprinkling your salad with toasted sesame seeds, chopped fresh parsley, or even a handful of chopped toasted walnuts or pine nuts. These garnishes add an additional layer of flavor and a delightful crunch that complements the soft roasted vegetables and creamy dressing.

Side Dishes

This salad shines as a versatile companion to many meals. Serve it alongside grilled chicken or fish for a well-rounded dinner, or bring it to the table as a star side at your next barbecue or potluck. It also pairs wonderfully with warm flatbreads or crusty baguettes to soak up any leftover dressing.

Creative Ways to Present

Try layering the roasted veggies and arugula in a clear glass bowl to showcase the beautiful colors, or serve the salad in individual small bowls for a charming touch at dinner parties. For a fun twist, toss on extra fresh herbs or a drizzle of extra tahini just before serving for a decadent finish. It’s great warmed or chilled, so play around with presentation based on your mood and occasion.

Make Ahead and Storage

Storing Leftovers

If you have any leftovers (and that’s a big if!), store the salad in an airtight container in the refrigerator for up to 3 days. Because the dressing coats the vegetables, it keeps them flavorful and moist, though the texture of the arugula may soften—consider storing the arugula separately if you want to maintain its crispness.

Freezing

We do not recommend freezing this salad because the texture of roasted potatoes and cauliflower changes after freezing and thawing. The fresh elements and tahini dressing also lose their vibrancy in the freezer. This salad is definitely best enjoyed fresh or refrigerated for a few days.

Reheating

To gently warm leftovers, place the salad (without arugula if stored separately) in a baking dish and heat in a 350ºF oven for about 10 minutes. Toss with fresh arugula and a drizzle of dressing afterward to revive the salad’s freshness. Avoid microwaving, which can make the potatoes gummy.

FAQs

Can I use regular tahini instead of well-stirred tahini?

Yes! If your tahini has separated, just give it a good stir before measuring. Well-stirred tahini ensures the dressing is creamy and smooth, but the dish will be just as delicious either way.

Is it necessary to use fresh tarragon? Can I use dried?

Fresh tarragon has a more vibrant, nuanced flavor that really makes the dressing pop. Dried tarragon can be used in a pinch but use less since it’s more concentrated. If you have no tarragon, fresh basil or dill can be an interesting substitution.

Can I make this salad vegan?

This recipe is naturally vegan, as all the ingredients are plant-based. Just double-check your tahini and olive oil to ensure they’re pure and unadulterated.

What other greens can I swap for arugula?

Spinach, baby kale, or watercress are excellent alternatives if you want to change things up. Each green will bring its own unique flavor and texture that still complements the roasted veggies and dressing beautifully.

How spicy is this salad?

It’s mildly spiced, mostly aromatic thanks to the coriander and cumin, with gentle heat from cracked black pepper—not spicy-hot. You can always add a pinch of chili flakes if you crave a kick.

Final Thoughts

I’m so excited for you to try this Roasted Cauliflower and Potato Salad with Tarragon Tahini Recipe because it’s one of those dishes that feels both luxe and approachable. Its combination of roasted textures, creamy tangy dressing, and fresh herbs makes every bite a celebration of flavors. Whether you’re cooking for friends, family, or just yourself, this salad will quickly become a go-to favorite. Happy roasting and savor every delicious forkful!
